Unity In response to a distress signal, Commander Chakotay lands
his shuttlecraft on a planet's surface but is viciously attacked. He's swiftly
rescued by a colony of formerly assimilated Borg and goes to extreme measures
when he allows their resident physician, Dr. Riley Frazier, to heal his neural
injuries by linking him to a remnant of the Borg Collective consciousness.
Meanwhile, after Janeway and her crew find a suspicious Borg ship disabled and
adrift in space with a thousand members of the powerful Borg race lying dead
aboard it, they transport one of the corpses to Sickbay so the Doctor and Kes
can perform an autopsy.

Scorpion, Part I The sudden appearance of a complex and deadly
bioform that destroys everything in its path forces Janeway to attempt the
unthinkable—an alliance with the Borg.

Scorpion, Part II The ship remains on Red Alert after Janeway,
in exchange for safe passage through space, reaches an agreement with the Borg
Collective to help them fight Species Eight Four Seven Two, a race more
malevolent than their own.
